scanner only goes to transmissions with IDs that match talk group IDs you have stored in the banks talk
group ID list which are not locked out.
Because EDACS scanning requires clear reception of the control channel at all times, EDACS systems
tend to have a smaller usable area. An external antenna can greatly improve EDACS scanning in a fringe
area. If you are having trouble scanning an EDACS system, try manually selecting the data channel. If you
are getting good reception, the scanner will indicate talk group CTL-01. Try changing your location or using
an outdoor antenna to improve reception.
Operation
TURNING ON THE SCANNER AND SETTING SQUELCH

2. To turn on the scanner, turn VOLUME clockwise. Welcome To Dual Trunking appears. After about 3
seconds, you hear a hissing sound.
3. Turn SQUELCH clockwise, just until the hissing sound stops.
4. To turn off the scanner when you finish, turn VOLUME counterclockwise to OFF.
Notes:
The scanner does not scan if there are no frequencies stored in channels. If the scanner does not scan
and you have already stored frequencies in channels, turn SQUELCH further clockwise.
If the scanner picks up unwanted, partial, or very weak transmissions, turn SQUELCH clockwise to
decrease the scanners sensitivity to these signals. If you want to listen to a weak or distant station, turn
SQUELCH counterclockwise.
If SQUELCH is adjusted so you always hear a hissing sound, the scanner will not scan properly.
To ensure the scanner operates properly while in the trunking mode, we suggest you set SQUELCH
using the above steps, even if the scanner is automatically muted.
STORING KNOWN FREQUENCIES INTO CHANNELS
Good references for active frequencies are RadioShacks Police Call, Aeronautical Frequency Directory,
and Maritime Frequency Directory. We update these directories every year, so be sure to get a current
copy. Also see the supplied Police Call Trunking Guide.
Follow these steps to store frequencies into channels.
1. Press MAN, enter the channel number where you want to store a frequency, then press MAN again. M
and the channel number appear at the upper left corner of the display (for example: M100).
